he wrote 80 pages a day

That's what it says right here, in Joan Acocella's New Yorker profile on Georges Simenon, a writer of crime novels, an inveterate womanizer.  Look for yourself.

Every morning, he sat down and completed his self-assigned daily quota of eighty typewritten pages. Then he would vomit, from the tension, and spend the rest of the afternoon relaxing.

I'm going to go to Body Combat now.  And I am going to think not about writing 80 pages a day—impossible!—but about how to start doing so many book things newly.  It's time.
